1.Rectifier operates at any of the rated supply voltages and frequencies without further adjustment.

2.At 305V input mains the UPS maintains the specified output voltage at rated load without discharging a previously charged battery

3.IEC 62040-3 / EN 50091-3: at rated load and input voltage 400V, battery charged

4.IEC 62040-3 / EN 50091-3: at rated load and input voltage 400V, battery charging at maximum rated power.
